having an average diameter of 2–3 nm. The thermally stable heterogeneous catalyst was successfully applied in Suzuki–Miyaura and copper-free Sonogashira–Hagihara coupling reactions of aryl halides under low palladium loading conditions. Reactions were proceeded in neat water without using any organic co-solvents. The catalyst was successfully recycled for the sample Suzuki–Miyaura reaction nine consecutive
